Answer: (2) 78 %
Explanation:-
The ratio of the number of boys and girls in a school = 3:2
Then, let the number of boys = 3 X  & number of girls is 2 X.
20 % of the boys = 3 X x 20/100
= 3 X/5

25 % of the girls = 2 X x 25/100
= X/2

The total scholarship holder students = 3 X/5 + X/2
= (6 X + 5 X)/10
= 11 X/10
The percentage of scholarship holder students = 11 X 100/10 x 5 X
= 22 %
The percentage of the student who do not get the scholarship  =  100 – 22
= 78 %
Hence, the answer is (2) 78 %.
